Understanding Your Business

he telecommunication industry is the most dynamic and rapidly expanding Tindustry in the world. This industry consistently faces challenges associated

with changes in technology, competition, installation, speed-to-market, zoning and

the ever-increasing density of cell sites. These issues require unique and

innovative solutions that allow service providers to bring new sites on line

quickly, economically and in an aesthetic and environmentally

friendly manner Providers, architects and engineers need a

knowledgeable and experienced source to address these

concerns with timely and unique solutions. Fibergrate has

applied our knowledge and experience with fiberglass reinforced

plastics (FRP) to the develop-ment of several standardized

systems for transmission site construction. In addition we work

to develop customized solutions for your specific problems. Fibergrate has

resources worldwide dedicated to working directly with the customer. From

specification and design to site inspections and installations, Fibergrate brings

superior products and unparalleled field and technical service directly to you.

Fibergrate’s productsare engineered toprovide long-term,aesthetically superiorsolutions for all areasin your facility.

Problems & Solutions

n the last 10 years the telecommunications market has progressed from basic Ianalog technology to broadband Internet access and wireless handheld devices.

This evolution in technology requires the rapid development and deployment of

new equipment and new sites for providers to remain competitive.

The global demand for bandwidth requires an ever-increasing density of cellular

transmission sites. Service providers are faced with the growing challenges,

especially in urban area of where to locate these sites. Weight, size and

appearance issues can mean the difference between securing a critical rooftop

transmission site and leaving a hole in a provider coverage area.

Fibergrate’s lightweight and electronically transparent platform systems are ideal

for installing transmission stations in areas that were previously thought

impossible due to weight or zoning.

Our standardized and custom camouflage screening systems reduce visual impact

of transmission antennas in urban and rural environments. These lightweight

systems can be fabricated to match any building facade.

Fibergrate is committed to working closely with service providers, architects and

engineers to provide the best solutions to this dynamic industry now and in the

future.

RF Transparent ScreeningFibergrate has worked with the world’s cellular providers to develop standardized camouflage screening systems for the cellular market.Fibergrate’s RF transparentsystems are lightweight, easy to install, corrosion resistant and can be installed to match any building facade. Fibergrate RF materials have been fully tested by Anechoic Chamber 800 MHz-2200 Mhz, RF attenuation through computer modeling and extensive field and drive testing. Typical RF attenuation loss is less than 1 dB.

Equipment AccessFibergrate’s handrail and safety ladder systems meet the need for long term durability, easy installation and worker safety. Our corrosion resistant, highly durable systems meet or exceed all OSHA requirements, are easily assembled on-site and are priced competitively with less durable conventional products.

Custom SolutionsWhether you are looking for new, lightweight, RF transparent solutions for antenna supports or upgrading an existing cell site that is not designed for the additional loading, Fibergrate has a team of engineers dedicated to working with you to provide site-specific solutions that address your needs.

BTS Support Platforms(Base Transmitter Stations)

Whether installing new 3G networks or upgrading existing networks, rooftop transmitter stations are a necessity. Fibergrate’s BTS support platforms are one-third the weight of steel and can be installed by hand, eliminating cranes, permits and restricted installation hours. A typical Fibergrate BTS can be installed in hours, instead of the days needed for a steel structure. Any modifications or on-site fabrications can be done using simple hand tools.

Fabrication Services

ibergrate combines engineering skills with an unmatched knowledge of the application of Fcomposite materials. Staffed by professional engineers, experienced fabricators and

project managers, Fibergrate’s fabrication group is well equipped to provide turnkey solutions

to a wide range of projects - from design and estimating to fabrication, final construction and

installation. Fibergrate’s experienced engineering group maximizes utilization of composite

components while meeting OSHA, BOCA, NFPA and other applicable building codes to

accommodate seismic, geographic or topographic considerations. As the leader in the use of

fiberglass composites in construction, Fibergrate offers a number of related services including:

� Conceptual design � Final engineered drawings � Engineering specifications � Customer design

As a measure of experience, Fibergrate has over 35 years in the engineering, design and

fabrication of FRP structures and over 30,000 successful installations worldwide. Projects

range from simple catwalks and stairways to engineered platforms, RF screening, antenna and

equipment support structures and other ancillary elements for cellular rollouts.

Fibergrate has developed both standard and custom RF screening solutions, compliant with all

building codes and certified by a Registered Professional Engineer. Fibergrate’s standardized

designs allow for the elimination of lengthy site design and fabrication, and give the

confidence of a certified structure to ensure an on air, on time rollout in the most cost-effective

manner.

®Fibergrate Standard Triangle Inside Square Design

For Alternate Azimuth Requirements

This drawing illustrates modifications to modify a standard square box into a triangle inside-a-square RF Screen. This design is used when the A&E firm wishes to maintain parallel lines between the building and the RF Screen enclosure, but needs to reach difficult azimuths. The two internal antenna support members could be infinitely variable to allow for almost any combination of azimuths. By keeping a triangle modification kit in stock, the carrier has the advantage of greater flexibility in changing a standard square into a more useful and fitting design at a reasonable cost and with a very simple modification.

®Fibergrate Custom Texture and Color Matching Technology

®Fibergrate offers many standard textures available to match exiting brick, stucco, CMU, or other common building materials. Custom textures are also available upon request. Fibergrate uses the highest quality polyurethane coatings to color match the outer textures to exiting building surfaces. All that is required is a color number from standard coating chip sets or a sample of the building wall facade required to be matched.

Comprehensive sample kits are available upon request for use in the field by Site Acquisition zoning or architectural personnel.
